TUBING BENDER.

Application filed {September 21, 1927. Serial No. 221,040.

This invention relates to a bending tool for pipes, tubes and the like, the general object of the invention being to provide a tool having a hollow body for receiving the article to be bent, with a socket part for receiving a handle, the body having an outwardly curved wall at one end for forming the curve or bend in the article.

Another object of theinvention is to provide a toothed jaw which projects from the curved wall for facilitating the bending of the article by the tool.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation showing the device in use.

Figure 2 is a top plan view of the device.

Figure 3 is a fragmentary sectional view throu h the bending part of the tool and through the jaw.

Figure 4 is a section on line d-lof Fig-- ure 1.

Figure 5 is a face view of the jaw member In these views, 1 indicates the hollow body of the device which is formed with a 45 tension 2 at one side thereof, said extension being connected with the lower end of the body, with said lower end sloping upwardly from the junction of the extension with the body, as shown at Said extension is formed with a socket 4 which has a slot 5 in one wall thereof. Ears 6 are formed on the extension, one on each side of the slot, and these ears are provided with threaded perforations to receive a bolt 7. Thus a handle 8 can be fastened in the socket by tightening this belt.

The body has an opening 9 in one side thereof and said body is of substantially horseshoe shape in cross section. At the junction of the extension with the body, the inner wall of the body curves outwardly and downwardly, as shown at 10, and in this curved wall a recess 11 is formed which has its axis in alignment with the axis of the extension. A circular jaw member 12 is held in said recess by the set screw 13 and the outer face of said aw member is formed with an arcuate shaped groove which is of curved shape in cross section and which is provided with the transversely arranged teeth 14.

From the foregoing it will be seen that by placing the body over a pipe, tube or the like, as shown at A, and pressing downwardly upon the handle of the tool, the article will be bent upon a curve, as shown in Figure 1. The curved groove conforms to the contour of the pipe or article being bent and its arcuate shape will conform to the curved bend being formed in the pipe or article. The teeth of the jaw member prevent the tool slipping on the pipe or article.

With this tool, a pipe or the like can be bent with but little effort and there is no danger of the device slipping on the article or of the article slipping out of the tool. The jaw should be a steel hardened one and as will be seen, it can be removed so that another one can be substituted for it, the curve in which is on a different degree so that a diiferent kind of bend can be made in the article.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

l/Vhat I claim is A, tool ben der compris ing a hollow body having an opening in one side thereof which communicates with the interior of the body with a lower internal wall of the body, at one end thereof, curving outwardly and downwardly,

said curved wall having a circular recess therein, a circular jaw member removably held in said recess and having an arcuate groove in its face of curved shape in cross section, with teeth on said face and a handle connected with the body, said handle extending obliquely from one side of the body,-

with the axis of the jaw member in alignment with the axis of the handle.

In testimony whereof I ailix my signature.

CLARENCE JOSEPH WILLGING.
